FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package otherwise
Functional when-otherwise conditionals
This package allows to replace PHP conditionals by an easy functional match-when-otherwise syntax.
Install
You can install this package via composer:
Usage
Every conditional match consists out of one or multiple when and one otherwise to provide values for each path.
match($value, ...$params): Match
This package provides a helper function match. The first value is the value to match against. You can pass a variable amount of $params which are passed to every callable that resolves a $result.
when($condition, $result): Match
$condition is a bool, a callable or a value to compare against (using ==). $result takes either some value or a callable for lazy evaluation. More specific conditions have to be defined first because the first match is the final result.
whenInstanceOf($type, $result): Match
This is just a shortcut method for $value instanceof A. $type is anything that can be on the left side of an instanceof operator. $result takes either some value or a callable for lazy evaluation. More specific conditions have to be defined first because the first match is the final result.
whenThrow($condition, $result): Match
$condition is a bool, a callable or a value to compare against (using ==). $result takes either an exception class name, an exception instance or a callable that returns an exception. More specific conditions have to be defined first because the first match throws the exception instantly.
otherwise($value)
$value is of type callable or some value. Supplies the default value if no when has evaluated to true before.
otherwiseThrow($value)
Throws an exception if no when has evaluated to true before. It takes an exception class name, an exception instance or a callable that returns an exception.
